DISK PLOW.

Specification of Letters Patent.

Application led September 27, 1913.

Patented May 12, 1914. serial No. F192,195.

To all 107mm, t may concern Be it known that I, WARREN W'. VVELLER, a citizen of the United States, residing at Hamilton, Ohio, have invented a new and useful Improvement in Disk Plows, of which the following is a specification.

This invention relates to disk plows of the class wherein one or more cutting disks are rotatively mounted on a suitable frame or beam supported on the usual ground wheels, and the objects of my improvement are to provide means for adapting the plow to a wider range of conditions of soil by combining a general purpose and a sod plow in one structure; to provide an auxiliary or turning disk for increasing the turning over of the soil, so desirable in the plowing of sod or in trashy ground; to provide means for adjusting the turning` disk in relation to the cutting disk, and to provide simple and durable construction and assemblage of the various parts for securing facility of operation and eficiency of action. These objects may be attained in the following described manner, as illustrated in the accompanying drawings, in which Figure 1 is a plan of a plow provided with my improved turning disk; Fig. 2, a front elevation of the cutting disk with the turning disk in operative position, and Fig. 3, an edge View of the turning disk and its adjustable connections with the beam and in relative position to the cutting disk.

In the drawings, 1 represents the beam of a riding disk plow supported on ground wheels 2, 3 and t. The seat 5 is supported on the rear end of the beam; the land wheel 2 is mounted on a crank axle G which is under control of the hand lever 7 the rear wheel 3 is swiveled on the rear end of the beam by means of the angular spindle S; the furrow wheel 4 has its spindle hinged at 9 on the axle 11 which is controlled by means of the hand lever 12. Said spindle being adjustably connected to the front end of the beam by means of the draft rod 13; and llt the rotary concave convex cutting disk mounted Ion the beam and facing outwardly therefrom, all being constructed and arranged in the ordinary manner.

A standard 14 formed with a foot 15 is adjustably secured on the beam by means of the bolt 16, and the depending bracket 17 provided with a bearing 18 is adjustably Secured to said foot with said bearing in a rearward and upward direction from the axis of the cutting disk. Said bracket terminatcs in engagement with the usual scraper 19 for the cutting disk. The turning disk 21 slightly concavo-convex in form is provided with a spindle on its convex face whereby it is journaled in bearing 1S with its concave face in an outward direction and in a plane at an oblique angle to the plane of the cutting disk so that the lower front por tion of its edge will almost contact with the concave surface of the cutting disk as shown in Figs. l and 3, and out of contact with the intervening scraper 19.

In operation, the disks are both journaled with their' concave faces in an outward direction and turned by the soil in a forward direction as shown by the arrows. The turning disk being about three-fifths the diameter of the cutting disk and having a more outward inclination its smooth concave face serves to continue the turning of the soil from the cutting disk a farther distance than would be possible by means of any stationary scraper however much it might be curved in an outward direction. rl`he clogging of the soil on a fixed scraper limits its turning thereof but the action of the soil on the moving surface of the turning disk keeps its surface cleanly scoured and per mits it to be further inclined in an outward direction with corresponding increased etliciency. ll`he almost universal adjustment of the turning disk in relation to the cutting disk by means of the standard and bracket adapts it for use in the greatest variety of soil conditions. The turningof theauxiliary disk under the action of the soil affords so little resistance thereto that the draft of the plow is n'iaterially lightened.

Having fully described my improvement, what I claim as my invention and desire to secure by Letters Patent of the United States is 1. A disk plow comprising a concave-com veX cutting disk, a similar disk of less diameter journaled in front of the cutting disk and in the rear of its axis, and with its plane at an oblique angle to the plane of the cutting disk for increasing the turning of the soil therefrom.

2. A disk plow comprising a concavo-convex cutting disk, a similar disk journaled rearwardly of the axis thereof and inclined in a forward and outward direction to the plane of the cutting disk and with its forward edge in near proximity to the face thereof for automatically increasing the turning of the soil in its passage from the cutting disk tliereoyer.

3. In a plow, the combination witli the concavo-conyex cutting disk of a similar oooperating auxiliary disk journaled rearwardly and upwardly from tlie axis olf the cutting disk with its face in the saine outward direction and at an angie to tlie face thereof for increasing the turning of the soil from the cutting disk.

4:. In a plow of the class described, a cut- `15 ting disk, an auxiliary disk adjustably sup- Gopies of this patent may be obtained for five cents each, by addressing the Gommssoner of Patents.
